The global energy crisis, coupled with the threat of climate change, demands innovation in the energy sector and responsible consumption in both developed and developing countries.
While cities around the world are pledging to make use of 100 per cent clean energy, Chinese cities have to follow this trend too by pushing for the introduction and development of recapturing released heat for power generation, and developing more renewable energy projects.
The EC-Link Project aims to support Chinese cities in addressing energy problems in cities and improving energy management in urban areas.
With Qingdao’s constant updating of its public transport vehicles, the number of pure electric buses the island city owns is increasing. Compared with fuel vehicles, there are certain unique operational skills that can be deployed for better use of pure electric vehicles. “In order to save energy, we must first ensure the vehicle and every part of it to be in the best condition at all times and that is the basis for energy saving,” said Mr. Wang Qun, a bus driver, who pays great importance to tire maintenance, engine room dust removal and air pump dust removal. He elaborated: “In operation, we must pay attention to road condition and traffic controls. For example, 3 traffic signal lights at the Xianxialing Road, East Yinchuan Road and Tong’an Road are synchronized at same intervals, 30 seconds apart. After the green light at Xianxialing Road intersection turns on, we should drive through the intersection of the East Yinchuan Road with constant speed and reach at a stop of the East Yinchuan Road. And then, we drive through the East Yinchuan Road with constant speed and enter the Tongan Road Stop where at this point of time, the intersection ahead would show a red light. After getting on and off of the passengers, we may get the right time to pass the intersection. By this way, we can optimally save lots of energy.” Wang Qun is a bus driver along the 501st route. After years of exploration and repeated tests, he found that the motor rev designed for the vehicle is 1000 rpm to 2000 rpm. And according to the bus operation, if the rev is between 1300 rpm and 1800 rpm and the speed is between 30km/h to 40km/h, it is the most economic.
According to statistics, Mr. Wang uses a special operation method to run 2,600 kilometers per month that can save 900 KWHs and annually save about 10,800 KWHs. Wang Qun has been recognized as one of the most economical drivers of Qingdao pure electric buses.
“The 501st route is with 41.7 kilometers and it passes through 64 stops, 12 primary and secondary schools and kindergartens, 6 hospitals, 2 business districts, and 97 intersections of which 37 have no signal lights, as well as 142 zebra crossings. Of the 64 stops, 19 are connected to the subways Line 2 and Line 3.” Because of his well knowledge of the road conditions, he used the unique ability of electric vehicles to recover electricity by reducing the vehicle speed in advance on the downhill section and using the method of “continuous speed reduction” and “segment speed reduction” to extend the braking time and braking distance, so to maximally recover power energy.
The 8th Exhibition of New Product and New Technology of Energy Saving and Emission Reduction in 2018 (New Energy Vehicle) and the 3rd Green Low-Carbon Industry Expo opened at the Guilin International Convention and Exhibition Center. The concept of low-carbon life and green travel has affected people’s behavior of car buying. New energy vehicles have attracted public attention at the exhibition.
The theme of this exhibition is “Energy Saving and Protecting Blue Sky”. The three-day exhibition has showcased new energy vehicles and new products and technologies for energy saving and emission reduction. There are four exhibition areas, namely, the new energy vehicle exhibition area, the energy-saving low-carbon exhibition area, the green building exhibition area and the green agriculture exhibition area.
In the next step, Guilin will take the ride of this activity to effectively promote green development, advocate a simple, green and low-carbon lifestyle, and carry out actions such as creating conservation-oriented governmental institutions, green families, green schools and green communities and facilitating green travel. It will formulate action plans, to enhance the role of energy conservation and resource conservation in accelerating the reform of ecological civilization system, building beautiful Guangxi and Guilin, showing Guilin afresh new face to the outside world and achieving results of the new actions. It will rationally adjust industrial structure, intensify elimination of backward production capacity, and continue to accelerate upgrading and transformation of the tradition industries, vigorously develop strategic emerging industries, accelerate the development of low-carbon service industries; stably promote energy conservation and consumption reduction, and develop low-carbon urban areas, low-carbon parks and low-carbon communities.
The European Commission’s latest reports on gas and electricity markets, which cover the last quarter of 2017, have just been published, containing a wide range of data about supply and usage of electricity and gas in the EU.
The electricity market report confirms that over the last few years electricity consumption in the EU has clearly been decoupled from economic growth. The EU’s GDP increased by almost 12% between 2010 and the end of 2017; over the same period, electricity consumption decreased by 4%. Moreover, in December 2017 more energy from wind was generated in the EU than ever before: 41 TWh (terawatt hours), equivalent to 16% of the EU’s electricity mix.
On September 19-21, EC-Link Project, with the support of MoHURD, EUD and the Hefei Municipality has organized an Inter-City Lab (ICL) focused on water management, solid waste management and clean energy sectors.
The event has seen the participation of 120 delegates representing 8 European cities (Barcelona, Berlin, Bordeaux, Hamburg, Liverpool, Mannheim, Valencia and Växjö), 7 Chinese provinces (Anhui, Guangdong, Guangxi, Henan, Hunan, Qinghai and Shandong), 9 Chinese municipalities (Changzhou, Guilin, Hefei, Luoyang, Nanjing, Qingdao, Weihai, Zhuhai and Zhuzhou), representatives from local and provincial academies and research centers, European and Chinese experts.
During the event, among the many speeches, Ma’am Tong Guichan, Director of the Division of International Cooperation of MoHURD, affirmed the crucial importance of sustainable development of Chinese cities and the strong support of MoHURD to EC Link Project; Mr. Wang Daorong, Deputy Director General of Hefei Municipality, stated the great commitment of Hefei City to develop more environmental sustainable projects and the great importance of events like Hefei ICL where Chinese cities have the opportunity to share their experience with multiple European ones; Mr. Andrea Claser, Team Leader of EC-Link Project, stressed the full commitment of the Project to be a key component for Chinese and European cities in order to share mutual experiences and hopefully develop long term cooperation; Mr. Florian Steinberg, Senior Urban Planner – EC-Link, provided important insights and specific examples about ongoing Chinese urban renewal and revitalization.
During the three days gathering, European and Chinese representatives have been sharing experiences and knowledge with the intent to create the so called City Network Units (CNUs); these new established working groups of Chinese and EU cities (CNUs) will work together to adapt selected practices/procedures to the Chinese urban context, so to allow an effective know how transfer.
In upcoming months, European and Chinese cities will work together with the intent to develop joint technical teams meant to be the baseline of long term cooperation programs and technology exchange in multiple areas such as: water governance and integrated river basin, zero landfill policy, renewable energy from bio-waste, urban storm water management, district heating from co-generating power plants, waste water treatment for the removal of harmful pollutants, municipal solid waste management, and many others.
